Description

Technical Field

[0001] The invention relates to the technical field of oil pump rotation control for a hydroelectric generator set, and in particular to an automatic oil pump rotation method, equipment and medium for a high-pressure oil system of a hydroelectric generator set. Background Art

[0002] The function of the high-pressure oil system of a hydropower station unit is to establish an oil film between the mirror plate and the thrust bearing of the unit through high-pressure oil, so as to prevent the slow rotation of the unit during the start-up and shutdown process, causing the thrust bearing to bear too much weight and cause the bearing surface or mirror surface to be worn or burned. Therefore, the stable operation of the high-pressure oil is very necessary for the stable operation of the unit. The rotation method of the pumps used in the current high-pressure oil system is mostly achieved by manually switching the mode handle. It has the ability to rotate, but the degree of automation is not high. If one of the oil pumps is operated as the main pump for a long time during the operation of the high-pressure oil system, it will be repeatedly started and stopped for a long time, which will cause equipment fatigue and reduce the service life. The standby pump is shut down for a long time, and the motor is easily affected by moisture and the insulation is reduced. In this way, it is impossible to regularly check the reliability of the oil pump motor and timely discover the failure of the standby pump, which is not conducive to improving the automation level of the unit and affects the start-up and shutdown of the unit. Therefore, in view of the deficiencies in the prior art, the present invention provides an automatic rotation method for the oil pump of the high-pressure oil system of a hydropower unit. This method mainly determines the available status of the high-pressure oil pump and selects different rotation methods according to needs to perform pressure building judgment on the high-pressure oil system, thereby realizing the start and stop commands of the high-pressure oil system during the start and shutdown process, improving the reliability and automation of the equipment, and improving the success rate of start and shutdown of the unit. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a method for automatically rotating the oil pump of the high-pressure oil system of a hydropower unit. The specific technical solution is as follows:

[0004] S1: Control device power-on initialization;

[0005] S2: Obtain the available status of the two high-pressure oil pumps, set the main pump and the standby pump according to the available status of the oil pumps, and if both high-pressure oil pumps are unavailable, output two high-pressure oil pump fault signals and a high-pressure oil system unavailable signal;

[0006] S3: monitoring the high-pressure oil start command, if the high-pressure oil start command is received, executing step S4;

[0007] S4: Start the main high-pressure oil pump. After the main high-pressure oil pump is loaded for a set time, determine whether the pump startup has timed out. If not, execute step S5. If so, execute step S6.

[0008] S5: Determine whether the currently started main high-pressure oil pump has successfully built up pressure. If successful, output a high-pressure oil pressure building success signal and execute step S9. If unsuccessful, execute step S6.

[0009] S6: Determine whether there is an available standby pump. If yes, start the standby pump and execute step S7. If no, output a high-pressure oil pressure build-up failure alarm signal.

[0011] S8: Determine whether the currently started standby high-pressure oil pump has successfully built up pressure. If successful, output a high-pressure oil pressure building success signal and execute step 9. If unsuccessful, output a high-pressure oil pressure building failure alarm signal.

[0012] S9: Monitor whether a command to stop the high-pressure oil system is received. If not, return to step S4 until the end; if received, stop the main high-pressure oil pump and the standby high-pressure oil pump, and reset the status signal.

[0013] Furthermore, in step S2, if both high-pressure oil pumps are unavailable, both high-pressure oil pumps are set to an unavailable state;

[0014] If only one high-pressure oil pump is available, the available high-pressure oil pump is set as the main pump and the standby pump is set to empty;

[0015] If both high-pressure oil pumps are available, the main pump and the standby pump are set according to the set rotation method.

[0016] Furthermore, if both high-pressure oil pumps are available, the rotation method is as follows:

[0017] The operation times of the two high-pressure oil pumps are obtained, and the high-pressure oil pump with the smallest operation time is set as the main pump, and the other high-pressure oil pump is set as the standby pump.

[0018] Furthermore, if both high-pressure oil pumps are available, the rotation method is as follows:

[0019] The operating time of the two high-pressure oil pumps is obtained, and the high-pressure oil pump with the shortest operating time is set as the main pump, and the other high-pressure oil pump is set as the standby pump.

[0020] Furthermore, if both high-pressure oil pumps are available, the rotation method is as follows:

[0021] The high-pressure oil pump that was started most recently is used as the backup pump, and another high-pressure oil pump is used as the main pump.

[0022] Furthermore, in step S4, the high-pressure oil analog quantity measured by the pressure sensor on the high-pressure oil pipeline is obtained to compare whether the measured value is greater than the set value, and to determine whether the pump startup has timed out.

[0023] Furthermore, in step S4, the high-pressure oil switch value measured by the pressure switch on the high-pressure oil pipeline is obtained, and the measured value is compared to see whether it is greater than the set value to determine whether the pump startup has timed out.

[0032] Example 1

[0033] Embodiment 1 of the present invention discloses a method for automatically rotating an oil pump in a high-pressure oil system of a hydroelectric generator unit, such as Figure 1 As shown, the specific steps are as follows:

[0034] S1: Control device power-on initialization;

[0036] In this embodiment, the two high-pressure oil pumps are respectively referred to as 1# pump and 2# pump for description;

[0037] Specifically, the state variable STA can be set, STA=0, indicating that both pumps are unavailable, and the fault flag of pump 1# is set, the fault flag of pump 2# is set, and the unavailable flag of the high-pressure oil system is set; STA=1, indicating that pump 1# is available and pump 2# is unavailable, and the normal flag of pump 1# is set, the fault flag of pump 2# is set, and the available flag of the high-pressure oil system is set; STA=2, indicating that pump 1# is unavailable and pump 2# is available, and the fault flag of pump 1# is set, the normal flag of pump 2# is set, and the available flag of the high-pressure oil system is set; STA=3, indicating that both pumps are available, and the normal flag of pump 1# is set, the normal flag of pump 2# is set, and the available flag of the high-pressure oil system is set.

[0038] Set the main pump and standby pump according to the available status of the oil pump;

[0039] As a preferred embodiment, the main pump and the standby pump are arranged as follows:

[0040] If both high-pressure oil pumps are unavailable, both high-pressure oil pumps are set to unavailable state;

[0041] If only one high-pressure oil pump is available, the available high-pressure oil pump is set as the main pump and the standby pump is set to empty;

[0042] If both high-pressure oil pumps are available, the main pump and the standby pump are set according to the set rotation method.

[0043] Specifically, if both high-pressure oil pumps are unavailable, that is, STA=0, then two high-pressure oil pump fault signals and a high-pressure oil system unavailable signal are output;

[0044] If STA=1, the main pump is selected as pump 1#, and the standby pump is none; execute step S3;

[0045] If STA=2, the main pump is selected as pump 2#, and the standby pump is none; execute step S3;

[0046] If STA=3, the main pump and the standby pump are set according to the set rotation mode, and step S3 is executed;

[0047] As a preferred embodiment, the rotation method includes rotation based on number, rotation based on time and rotation based on order;

[0048] The rotation method based on the number of rotations is as follows:

[0049] Obtain the operation times of the two high-pressure oil pumps, set the high-pressure oil pump with the smallest operation time as the main pump, and set the other high-pressure oil pump as the standby pump;

[0050] If STA=3, when the number of times pump #1 runs ≤ pump #2 runs, pump #1 is set as the main pump and pump #2 is set as the backup pump; when the number of times pump #1 runs > pump #2 runs, pump #2 is set as the main pump and pump #1 is set as the backup pump.

[0051] The rotation method based on time rotation is as follows:

[0052] Obtain the operating time of the two high-pressure oil pumps, set the high-pressure oil pump with the shortest operating time as the main pump, and set the other high-pressure oil pump as the standby pump;

[0053] If STA=3, when the running time of pump 1# is ≤ that of pump 2#, pump 1# is set as the main pump and pump 2# is set as the backup pump; when the running time of pump 1# is greater than that of pump 2#, pump 2# is set as the main pump and pump 1# is set as the backup pump.

[0054] The rotation method based on the order is as follows:

[0055] Set the most recently started high-pressure oil pump as the standby pump and set the other high-pressure oil pump as the main pump;

[0056] If STA=3, when the running time of pump 1# is ≤ that of pump 2#, pump 1# is set as the main pump and pump 2# is set as the backup pump; when the running time of pump 1# is greater than that of pump 2#, pump 2# is set as the main pump and pump 1# is set as the backup pump.

[0057] S3: monitor the high-pressure oil start command. If the high-pressure oil start command is received, execute step S4; if the high-pressure oil start command is not detected, continue to wait until the high-pressure oil start command is received, and then jump to execute step S4;

[0058] S4: Start the main high-pressure oil pump during the startup process or shutdown process. After the main high-pressure oil pump is loaded for a set time, determine whether the pump startup has timed out. If not, execute step S5. If so, execute step S6.

[0059] As a preferred embodiment, whether the pump startup has timed out is determined by parameters collected by a pressure sensor on the high-pressure oil pipeline or by parameters collected by a pressure switch, and the determination process is as follows:

[0060] Based on the parameters collected by the pressure sensor on the high-pressure oil pipeline, a timeout judgment is performed, as follows:

[0061] Obtain the high-pressure oil analog quantity measured by the pressure sensor on the high-pressure oil pipeline and compare whether the measured value is greater than the set value to determine whether the pump startup has timed out;

[0062] Based on the parameters collected by the pressure switch on the high-pressure oil pipeline, a timeout judgment is performed, as follows:

[0063] Obtain the high-pressure oil switch value measured by the pressure switch on the high-pressure oil pipeline, compare whether the measured value is greater than the set value, and determine whether the pump startup has timed out.

[0064] S5: Determine whether the currently started main high-pressure oil pump has successfully built up pressure. If successful, output a high-pressure oil pressure building success signal and execute step S9. If unsuccessful, execute step S6.

[0065] S6: Determine whether there is an available standby pump. If yes, start the standby pump and execute step S7. If no, output a high-pressure oil pressure build-up failure alarm signal.

[0066] S7: Start the standby high-pressure oil pump. After the standby high-pressure oil pump is loaded for a set time, determine whether the pump startup has timed out. If not, execute step S9. If so, output a high-pressure oil pressure build-up failure alarm signal.

[0067] S8: Determine whether the currently started standby high-pressure oil pump has successfully built up pressure. If successful, output a high-pressure oil pressure building success signal and execute step 9. If unsuccessful, output a high-pressure oil pressure building failure alarm signal.

[0068] Here, the process of steps S4-S8 is described in the case where STA=3, the main pump is pump 1#, and the standby pump is pump 2#;

[0069] 1# pump, after starting the pump and loading for a period of time, by comparing the measured high-pressure oil analog value or high-pressure oil switch value with the corresponding set value, it is determined whether the start-up of 1# pump has timed out. If not, it is determined whether the pressure of 1# pump has been successfully built up. If so, a high-pressure oil pressure building success signal is output, and step S9 is executed. If the pressure building is not successful, the 2# pump as the backup pump is started (when STA=1 or STA=2, if the pressure building is not successful, a high-pressure oil pressure building failure alarm signal is directly output), and it is determined whether the start-up of 2# pump has timed out. If so, a high-pressure oil pressure building failure alarm signal is output. If not, it is determined whether the pressure of 2# pump has been successfully built up. If so, a high-pressure oil pressure building success signal is output, and step S9 is executed. If the pressure building is not successful, a high-pressure oil pressure building failure alarm signal is output.

[0070] S9: Monitor whether a command to stop the high-pressure oil system is received. If not, return to step S4 until the end; if received, stop the main high-pressure oil pump and the standby high-pressure oil pump, and reset the status signal. The reset status signal includes a reset high-pressure oil pressure build-up success flag and a reset high-pressure oil pressure build-up failure alarm flag.
